What are the potential side effects of the treatments, and how can they be managed or minimized?

I'm entering the realm of breast cancer treatments, and I've heard that side effects can be quite challenging. Could those of you who have walked this path share some firsthand experiences with the potential side effects? More importantly, I'm curious to know how you navigated through these effects. Were there practical strategies, lifestyle adjustments, or even emotional support that helped you manage or alleviate these challenges? Your insights would not only equip me with valuable knowledge but also provide reassurance as I prepare for what's to come.
